Participant randomisation Once recruited, participants will be randomised to the control group ("standard" volume) or experimental group (patient determined volume). Randomisation will be achieved by participating physiotherapists telephoning a recruited Stirling Royal Infirmary physiotherapy department secretary at the end of the initial consultation. The secretary will randomly draw sealed opaque envelopes detailing the number of repetitions to do per day and inform the participant directly. As well as written documentation provided at the initial consultation the participant will be reminded not to discuss the volume of repetitions with anyone potentially participating in the trial or with the participating therapist for the duration of testing. In this way the participants, participating therapists and researcher will be blinded to group allocation. Any questions participants may have will be directed to the independent supervisor of the project (Frank Gilroy, Physiotherapy Manager, Forth Valley NHS Trust).
